I came across a task in which I had to complete different sentences by putting correct case indicators. Everything seemed to be fine until I reached a sentence which made me think a lot about what case indicator to put. So, the sentence is this:
私の答えは山口さんの答え (case indicator) ちがいます。
At first I thought that と would be a good option because I saw this sentence "私とちがう考えの人はいませんか". I'm not sure whether this is actually related to my situation but it seemed to be a good enough. I also was considering ほど to be put there but since it only can be used with a negative form of predicate, this is not the option I need. Now I think that it's が but am not sure.
P.S. I'm having zero problems with comparative constructions that use より, の方, etc. so far, but the one I mentioned above makes me ask a lot of questions.
P.S.S. I also would like to know what case indicators work with this verb and their meaning.
